7 Referring to the accompanying'drawings, illustrating by way of example one embodiment of the invention, means are provided for traveling and stopping a shape relatively to the punching mechanism to properly locate the perforations in the shape, and said traveling and stopping devices are preferably under the control of settable distance determining devices, an embodiment of such devices being illustrated and described in application 'Ser. No. 814,380, of T. P. Payne, filed January 26, 1914:. v Said devices are not" shown in detail herein, but the forwarding rollers 1 travel the beam along its pathway past the punching mechanism, and the head2, against which the forward end of theshape x abuts as it is impelled forward bythe rollers 1 is connected to the rack bar 3, which rack bar is connected to and controlled by the distance determining devices notshown in detail in this case.

Means are provided by the invention whereby the two flanges of the beam are simultaneously punched in accordance with the indications of the distance determining devices. According to certain features of so far as concerns certain other features of the invention other than-hydraulic means could be used to operate the punches.

In the embodied form a suitable supporting frame is provided, comprising vertical frame plates 10 and 11, which plates are tied together by cross frame plates 12 and 13. I i

The plates 10 and 11 are centrally apertured to permit the beam w to travel through.- Mounted upon the plates 1.0 and 11 are horizontally arranged guideways, a pair of gu deways 14 and 15 being arranged one above the other on the plate 10, and an opposed pair of guideways 16 and 17 being mounted one above the other upon the plate 11. Supported and guided by said guides 14, 15, 16 and 17 are two cross heads 18 and r 19, which support various parts of the punching mechanism, and are movable together and also relatively to each other for purposes hereinafter described.

Uponthe cross head 19 is mounted the punches for one of the shape flanges, being the righthandone referredto Fig.1. The punches Y20 and 21are carried in the supporting block 22 fixed to or integral with the cross head 19. v Said punches and reciprocate in guiding apertures f in blocks 23' and 24. The block 23 is carried on' a sup port 25 and has a dovetail connection therewith whereby the blocks 28 arerepl'a ceab'le',

The" block 40 is carried by. a dovetail connection onfia support :42, whichr'support'is slidably 7- mountedon shaft 27. -Theblock 41 Y has. like froina wise af'dovetail connection with'a support 48,, slidably" supportedron'shaft, 33.- The various dieblotks are :suitably: apertured to permit'thenpunchings 'to' drop away there Means. are provided the: invention for n'ifoving the die blocks together or tindepend= ently both to separate the blocks or. to draw them together vertically, referred to Fig/l,

"and' to movethem together, vertically," referred to Fig.1, to change their center. In

.the'einbodied form of. such means, 'a suitable drive is. provided,"zsuch as a inotor'44 driv mg a shaft '45,; carrylng a worm 46 (Figs? -3, 7 and" 8). Said worm' engages a worm" wheel'47 splined on .a-vertical'shaft 48, which shaft is carried in supporting blocks 49 and 50'ongthe frame, said shaft 48 being vertically slidable. in said blocks. The shaft 5 =48 is threaded right and-left. A nut 51' on: shaft 48*connect's to a pin "52' which pin passesthroughthe die'block 41.1-The head ofthe-pin 52? fits in azblock which Works in a slot 53formed in arms fixed to nut 51,

' thereby i'permitting horizontal" movement of 52-:i sa bell crank lever'56, having a'h'o rizon the block "41 relatively to the nut 51. A similar nut-54 is on the other thread on shaft '48, and has i similarsf connection with a pin 55,

passing through die block'40r Fast topin tal 'armadapted to engage the' upper edge oftheibeam flange,=theother arm '57 of's'aid bell crank being slotted and extending spondin-g bell-'crank'lever 58, with a horizontal arm adapted to engage the lower end Ofthebeamflange. The other arm 59 of said bell crank is slotted and extends up wardly past the slotted arm 57 ofbell" crank 56. Passingthrough the slots in arms 57 and 59 of the two bell crank levers is a pin 60. The pin 60 is-fixed to a'bifurcated slide 6l",r straddling shaft 48 andpslidablyr'supported-- by colla'rs 62 and-63 on said shaft.

In"an-apertu,re in'slide 61 Works a pin 64 fixed-to a rod 65 slidable in 'a support 66' on themachine"frame; Fixed torod 65 is a plungeru67 working in a cylinder 68, andacted'on'by a suitable pressure fluid. A suitable'pipe-69 connects to the main valve for the "punch; lie suitablerestoring spring; "('0v A support "71 limits the. downward movement of nut .54 to a position corresponding to the bottomredge of the fed-in beam lflange The manner of operation nism just described is substantially as follows The 1n0tor:-"44 controlled preferably.

The clamping Ofthe-i beam -flange; I through themovement I imparted to-pins 52 and-55 brings the-punch and die blocksto center or'proper position:

for punching) ASth-edieblocks 4O and-41 are centered, they move the corresponding shaftsz'27 and 33 up ordown and thus also center the-dieblocks28 and 24 for the-other beam flange, together with their punches. The varlous punches workin apertures inthe die-blocks, as will be later'more fully describedfandf are thus centered with themr The clamping and centering occurs at every punching operation, but the adjustment for size need be efl'ected only at a change in the size of beam operated upon. When a larger size of beam is to be taken in, the motor 44' is run in the opposite direction, and the nuts 51 and 54 travel slightly apart. The nut 54 coming to rest on support 71, the shaft 48 is moved upwardly until the mechanism is brought to position preparatory to receiving the new beam. I

cans are provided by the invention for positioning the punches and die blocks for beams of different depths or sizes. In the embodied form of such means, the right hand die block and punches are traveled horizontally (referred to Fig. 1). Upon the cross head 19 is carried a punching head 80. In said head are one or more slots 81 into which project the heads 82 of the punches 21 and 22, (Figs. 1 and 10), the punch heads 82 being mounted in the die blocks 23 and 24 to reciprocate in punching the work. Gags or interponents are provided for selectively operating the punches, and as embodied (Fig. 10) cross slots 83 are formed in the head 80 in which slots 83 reciprocate gags 84. The gags 84 have beveled ends 85 adapted to pass beneath or behind the heads of the punches as the gag slides into position behind the punch. The gags 84 have rods 86 connected to actuating levers 87, whereby the gags are slid into and out of operative position with respect to their punches. The levers 87 are actuated by solenoids 87 controlled from the distance record strip such as is shown in said copending application, Ser. No. 814,380, or they may be actuated manually if desired. The left hand punching head 88 (referred to Fig. 1) is fixedto the plunger of the actuating cylinder. The punching head 88 is provided with punches 21 and 22, and with gags and other cotiperating parts, similarly to the head 80 already described.

The cylinder 89 is carried on cross head 18, the plunger 90 working within the cylinder, and the pressure fluid being admitted and exhausted through conduit 91. Fixed to cylinder 89 are upwardly and downwardly projecting brackets 92 and 93. Upon the cross head 19 are corresponding upwardly and downwardly projecting brackets 94 and 95. Mounted to rotate in bracket 93 is a shaft 96, and said shaft has screw thread engagement with bracket 95. A shaft 97 is similarly rotatably carried by bracket 92 and has similar screw-thread engagement (not shown) with bracket 94. .Theshafts 96 and 97 are driven in unison by suitable means such as sprocket wheels 98 and 99, mounted on the respective shafts, and having a sprocket chain 100.

A. suitable drive is provided, and in accordance with one feature of the invention, moans controlled by theautomatic distance :wardly extending arm 126.

record, previously referred to, are provided and such means as embodied comprise a motor 101. Motor 101 drives by means of a sprocket chain 102, a friction drive, which operates a solenoid controlled positioning wheel or disk 104, which connects by a sprocket chain 105 to one of the shafts 96 or 97. The solenoids 106 may be connected to the distance record device and be controlled thereby.

Means are provided for bringing the die blocks firmly against the flanges preparatory to punching. As embodied, wedges and 116 are forced in between the respective pairs of die blocks, the wedge 115 forcing the die blocks 24 and 41 apart and firmly against the inside of the beam flanges. The wedge 116 operates in a similar manner be tween the die blocks 23 and 40. In the embodied form of means for operating. the wedges, said wedges are formed with legs 117 and 118 extending back from the body of the wedges and within the hollow interior of the dieblocks 25 and 26. Pivoted to legs 117 and 118 are links 1.19 and 120. The wedges 116 are reciprocable in guides 121 in the respective die blocks. Connected to links 119 and 120 is a yoked lever 122 also positioned within the hollow die blocks 25 and 26, which lever 122 connects across from one side of the machine to the other, and also to the actuating means. Yoked lever 122 has arms 123 and 124, connecting respectively to links 119 and 120, and has a downwardly bent connecting yoke 125, and an up- Lever 122 is pivotally mounted at 127 and 128, and is actuated by means of a fluid pressure cylinder 130. Cylinder 130 is mounted on cross-head 19. The piston rod 131 of said cylinder connects by a pivoted link 132 with arm 126 of lever 122. Cylinder 130 is provided with ports 133 and 134, connecting to suitable valve controls with a source of pressure fluid supply. As embodied, the port 133 is under constant or continuous pressure and the port 134 is connected to the main operating valve of the punch. Springs 135 act to move die blocks 40 and 41 slightly to the right (referred to Fig. 1) to receive each new beam and act as a cushion for the action of wedges 116. v

The invention provides, in accordance with one of its features, for varying the size of the wedges for beams of different depthsv or sizes, and in accordance with one feature of the invention, such variation in size of the wedges is automatically effected. As embodied, a plurality of auxiliary wedge members are provided which are automatically presented by the machine in requisite number for interposition withthe wedges 116 between the die blocks for the two flanges. In the embodied form, a set of such interponents or fillers 136 is provided for both frames 143., Theframes 143 thereby have a vertical movement (referred to Figs. 1, 4,

sides of the beam and maybe the same or similar in construction. The carriers 42 and 43are'hollow, the interp'onents 136 being located therewithin.

WVhen in the inoperative position, the interponents are supported on horizontal guides 137 and 138 formed on the inner vertical walls of thecarriers 42 and 43. The interponents 136 are cut away centrally into yoke shape With the central part extending downwardly (Figs. 1, 4,5 and 6). In said central cutaway; portion is a sleeve 139 having ateither end collars 140 and 141 which prevent longitudinal displacement of theinterponents from'the sleeve. The interponents are removablevertically by means to be described, Slidable on vertical guides 142011 the frame plates 10 and 11 are frames 143, two above and two below (Fig. l) for "eachs'et -of interponents, and each having vertical arms 144and 145 and at the bottom a horizontal connecting faceor reach 146, provided witlr guides 147. and 148,

adapted to receive the interponents from the guides 137 and 1380f thesupports 42 and 43 '(Figs' 1 and 6). The frames 143 are vertically slidable to carry the interponents from the inoperative or supply position into position betweenthe die blocks. 7

The frames 143 are operated by means of pins-149 (which also serve as pivot points between links 119 and 120 and yoke lever 122); The pins-149 project through curved slots 150 in both sides of the die block carriers 25 and 26, and into slots 151 in the cross or horizontalreaches of the respective 5 and 6) whereby their guides 147 and 148 for theinterponents pass into alinement-with guides 137 and 138 to'receive from and to return to the latter the requisite number of the jinterponent units, and in the intervening time'frames 143 carry the interponents down 5 between the'die blocks to 'coeperate with the wedges"115 and 116 while the flanges are beingpunched.

'Means are provided for keeping the inter-' ponents-to position, and as embodied, the

collar'141 is loose upon sleeve 139. A spring l52is coiled about sleeve 139 and Works between loose collar 141 and a fixed collar 153.

The-downward travel ofthe interponents when" carried by frames 143 is suchthatthe interponents-on the frames have their ends still in horizontal 'alinement (Figs; land 6) with the interponents remaining on'the guides 137 and 138 of the supports 42 and-' 4.3,{a'nd thus prevent the interponent units passing or lnterferlng w th each other.

Means are" provided for presenting the proper number of "interponents dependent upon the degree of separation ofthe die blocks'and-the depth or sizeof the beam to -beWpunch'ecL In -the embodied form, the

vent the nuts froniturning.

In accordance withbnefe'ature of the in vention, there is incorporated'with the foregoing'means, as embodied, devices for easing, away die blocks 23 *and '24 from the work. Such devices comprise angle plates 157 fixed to frame plates 10 and 11, and having rods 158 and 159 fixed thereto, re-

spectively, and extending through apertures Such screw-threaded portions 154 engagenuts 155, which have wings 156 which en-i gage the frame plates 10'and 11, and pre in the corresponding wings 156 of nuts 155- Springs 160 are coiled about bolts 158 and 159 and are in compression between the heads of bolts 158 and 159 and thewings 156 of nuts 155. The springs are sufiiciently strong to prevent movement "of the nuts 155 except when the wedges are-inserted or withdrawn. The collars 140- serve not only to holdtheinterponents 136 onthe sleeve but also connect the sleeves 139*and the 1 supports 25 and 26 for-the die blocks 23 f and 24;

Suitable restoring means for bringing thecylinder 89 and plunger back toposition after the punching operation are provided,

and as embodied, wings 162 are fixed to-x plunger 90." Fixed to wings 162 are rods I v 163,- extending through pockets 164fixed relatively to cylinder 89. Springs 165 are coiled around rods 163 and arein compression between the ends of pockets 164 and nuts 166 on the ends of rods 163. A stop 167acts against one of the wings 162;

The manner of operation 'of' the mecha' nisms described will be clearly understood from the-statements and explanations made in connection with'th'e various groups of mechanism. It may be generally stated, however The die blocks are centered and positioned or gagedto properly locate the punch holes in the flanges, as already described. In positioning the mechanism for the de'pthof only the right-hand die blocks 23 and 24 are traveled. This travel is effected by the rotation of-shafts96 and 97, from motor 101, controlled by the distance record sheet,

slots 150 and 151 by the pressure on the cylinders 130, the pistons being at the right hand end of the cylinders (Fig. 1) at this time. Thus'beams of varying depths are received with their flanges in the recesses of the four die blocks, and the die blocks also having been vertically centered and positioned as already described. The travel of the beam longitudinally through the ma chine and its stopping to properly locate successive punchings along the beam or shape are effected by the head 2 and rack bar 3, which head and bar are controlled by the distance determining device. Said device may be controlled by a distance record strip or a keyboard,'or otherwise. The

wedges 115 and 116 are driven in between the corresponding pair of die blocks (considered horizontally of Fig. 1) by the pressure being admitted through ports 134 into cylinders 130, which drives the pistons and their rods 131 to the left in Fig. 1. This swings yoke levers 122 and drives in the wedges 115 and 116. slid inwardly at the same time, through the engagement of pins 149 in slots 151 in cross pieces 146 of the frames 143. If supports 25 and 26 have been moved to the right sufficiently (dependent on the size of the beam to be operated upon) one or more of the interponents 136 have been moved from the guides 137 and 138 on supports 42 and 43 onto the guides 147 and 148 on frames 143, by reason of sleeves 139 also traveling to the right with supports 25 and 26. Thus the required number of interponents are interposed or driven in together with the wedges, to firmly draw the die blocks against the inner faces of the beam flanges, acting against springs 135 and 160.

The punching is effected on the clamped beam by the fluid pressure entering cylinder 89. The plunger 90 advances to the right (Fig. 1) until the punches carried thereby are against the beam flange, and the cylinder is moved to the left (inFig. 1)' until the punches carried by the opposite die blocks (at the right Fig. 1) are thereby brought against the opposite beam flange. The fluid pressure is then exerted against both' the cylinder 89 and the plunger 90 to effect the punching of the beam flanges. Suitable slots are made in the die blocks to discharge the punchings. As embodied, the'pressure in the cylinder 130 is accumulated or built up prior to the punching cylinder and plunger being brought into action, and they may thereby be operated and controlled from and by a single valve. This valve be in turn controlled or operated automatically from a distance record strip or like device.

After the punching, the controlling valve is reversed, automatically or otherwise, exhausting the pressure. The cylinder 89 and plunger 90 are returned to initial position Frames 143 are all by action of springs 165 as already described, and all the punches are thereby withdrawn from the punched holes in the flanges- The pressure in ports 134 has also been cut off and the pressure in ports 133 acts to move the pistons and piston rods 131 to the right (Fig. 1) withdrawing wedges 115 and 116 and also moving away frames 143 and thus likewise withdrawing interponents 136. The casing of the die blocks back'from the flanges has already been de scribed. The lever arms 56 and 58 are also rocked apart, thereby'unclamping the beam, as already described. The beam or shape is free to be traveled forward and positioned for the next punching in accordance with the setting of the distance determining device.

It will be understood that changes may be made from the actual mechanisms shown and described, without departing from the principles of the invention, and without sacrificing its chief objects and advantages.
